Parker 16 HL6-S Swivel Union 1 Inch Od Orfs 6000 Psi

Product Description

The PARKER 16 HL6-S is a compression tube swivel union designed for high-pressure hydraulic and fluid system applications. It connects two tube ends using an O-Ring Face Seal (ORFS) end connection with a UNF thread standard, providing a leak-resistant joint well-suited to demanding service environments. Built from steel, this fitting handles a maximum working pressure of 6000 psi. The swivel design allows rotational movement during assembly, reducing torque transfer to the tubing and making alignment easier on tight installations. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers.

This swivel union is intended for use in hydraulic lines, industrial fluid circuits, and related high-pressure plumbing systems where a 1 inch tube outside diameter is required. The ORFS end connections are widely used in mobile and stationary hydraulic equipment to minimize the risk of leakage at connection points. It is sold individually and is appropriate for both new installations and field repairs where an existing ORFS swivel union must be replaced.

Key Features

• 1 inch tube outside diameter for direct tube-end connection
• O-Ring Face Seal (ORFS) end connections with UNF thread standard for leak-resistant sealing
• Maximum working pressure of 6000 psi for high-pressure hydraulic service
• Steel construction for durability in demanding fluid system environments
• Swivel design reduces assembly torque and simplifies tube alignment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for hydraulic and high-pressure fluid systems requiring a 1 inch OD compression tube swivel union with ORFS end connections.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician familiar with high-pressure fluid system assembly. Depressurize and isolate the hydraulic circuit completely before removing or installing any fittings. Inspect the O-ring for damage before assembly and ensure mating face surfaces are clean and free of debris. Follow the equipment manufacturer's assembly procedures and applicable fluid system codes for torque and connection requirements.
